datAshur SD KeyWriter Manual v1.2
2. Setting your datAshur SD Master Device
datAshur SD KeyWriter application clones all critical security parameters including the randomly generated encryption key,
all PINs and administrator defined configurations between the Master datAshur SD drive and as many secondary datAshur
SD drives as required using any off the shelf USB hub (we recommend using a 10 port USB hub), allowing authorised
users to securely share data stored on iStorage microSD cards with one another. The software has zero visibility of both
the session key and decrypted data, making it impossible for a hacker to access or retrieve any critical security parameters
stored within the datAshur SD drive.

Important!
Before Cloning: As you will be cloning all security parameters from one datAshur SD drive (Master Device) to any number
of secondary datAshur SD drives, it is important to ensure the ‘Master Device’ has been pre-configured by the administrator
to include as many of the following configurable features.
Please refer to the datAshur SD user manual for detailed instructions on how to configure the datAshur SD drive.
Setting the Master Device
Note: The Admin PIN is automatically cloned from the Master device to all connected secondary drives.
Note: If your datAshur SD drive has been disabled from cloning, refer to section 39 of the datAshur SD user manual for
detailed instructions of how to enable KeyWriter cloning and configuration of all the other security features.
Remember: You will be required to enter your KeyWriter PIN each time you launch the datAshur SD KeyWriter
app. This is the PIN that was sent in an email to you together with the license number. The KeyWriter app PIN can be
changed see section 4: ‘Change your KeyWriter PIN’. In addition, ensure your ‘Master Device’ is unlocked and
connected to your computer before setting the Master device.
